Rules Index4. Stones(1) Curling stones shall be of circular shape. (2) No stone, including handle and bolt, shall be
of greater weight than 19.96 kg (44 lbs.)
or of greater circumference than 91.44 cm (36 inches)
or of less height than 11.43 cm (4.5 inches). (3) If a stone is
broken in play a replacement stone shall be placed where
the largest fragment came to rest. The end in play and the
game shall be completed using the replacement stone. (4) A stone that rolls over in its course or comes to rest on its side or top shall be removed immediately from play. (5) Where the handle of a stone quits the stone in
delivery, the player is entitled to replay the stone, if
the delivering team so desires. The handle must be
completely separated from the stone. (6) A stone that does not clear the farther hog
line shall be removed immediately from play except where it
has struck another stone lying in play. (7) A stone which comes to rest beyond and lying
clear of the back line shall be removed from play
immediately. (8)A stone that hits a side board or touches a
side line shall be removed immediately from play. (9)
No stone(s) shall be measured by instrument until the last
stone of the end has come to rest except by the umpire,
when requested by a skip, to decide whether or not a stone
is in play, or whether or not a stone is in the house when
the "Free Guard Zone' system of play is being used. If
the position of the rocks in the house makes it impossible
to use the 6‑foot measuring device to decide whether
a stone is in play at the 6‑foot position, the umpire
will do this visually and his/her decision will be final. (10) All sixteen stones assigned to a given sheet shall be delivered at each end unless the players in charge of the house have agreed upon a score for the end or the game has been conceded. 5. Teams(1)
At the start of a competition every team shall be composed
of four players, each player playing two stones and playing
each stone alternately with his/her opponent. (2)
No player shall use footwear or equipment that may damage
the surface of the ice. USCA Interpretation: No
player shall cause damage to the ice surface due to
footwear, and and/or body prints. (3)
The rotation of play established in the first end shall be
observed throughout the game. (4)
Prior to the game, the opposing third players shall
determine by lot which team shall lead at the first end
after which the winner of the proceding and shall lead. (5)
Where a player is unable to continue to play in a game or to
play at the start of a game, his/her skip may: (a)
finish the game then in progress and start any subsequent
game with the remaining players, in which case the first two
players shall throw three stones each; or (b)
bring in a qualified substitute for the game then in
progress at the beginning of the next end, or at the start
of any subsequent game. A qualified substitute is a person
who meet* the criteria for that competition. Any substitute
must play in the position of the replaced player when
entering a game in progress. (c)
commence the game with three players because one player is
late, and the late player may enter the game in the next
end, in his/ her normal position. (6) A player who has left a game because of illness, accident or other extenuating circumstances may rejoin his/her team at any time during any game in the competition, provided the rotation of play for the end in progress is not altered. If a substitute was selected the player may rejoin his/her team for the next game. (7)
No team shall substitute for more than one of the original
players in a competition (or one male and one female in a
mixed competition). However, any number of substitutes for
that one player (or couple in mixed) is allowed. |
